(Closed) Shower drama making me sad

My bridesmaids are my two sisters and FI’s two sisters..I’m very close to my two sisters and I always thought I was very close to my FI’s sisters as well (FI and I have been dating for almost 6 years). The girls are planning my bridal shower amongst each other (I asked not to be involved bc I’m super busy with other stuff right now..long and nonrelevant story haha).

Anyway, the mom’s have been cc’d on the emails for the shower as well and my mom accidently forwarded the chain to me, meaning to email me separetly (she’s not tech-saavy at all and I actually don’t even think she knows now that the rest of the email chain was on there).

I of course read the chain (I knew I shouldn’t have, but I did) and I’m feeling a little annoyed (which has transitioned into hurt) with how they’re reacting with each other. It shounds like my sisters are being too bossy but they’re trying to make it a nice event and his sisters just don’t really want to spend the time or money on it. It’s all very passive aggressive but the cues are definitely there. And they’re not even really working together (it’s like a two teams..my sisters vs his).

I didn’t know there were any problems regarding the shower and I was getting so excited about it (and I’m not one to get excited about these things) and now I’m just feeling sad. I don’t even want a shower if it’s going to cause problems and if people are going to have to spend money or time that they don’t want to!

My shower is this weekend and I don’t know how to act. Advice? Thanks bees!
